The primary treatment goal for patients with femoroacetabular impingement syndrome, a common hip condition in athletes, is to improve pain and function. In selected patients, in the short term following intervention, arthroscopic hip surgery is superior to a pragmatic NHS- type physiotherapy programme. Here, we report the three-year follow-up results from the FemoroAcetabular Impingement Trial (FAIT), comparing arthroscopic hip surgery with physiotherapy in the management of patients with femoroacetabular impingement (FAI) syndrome.

Two-group parallel, assessor-blinded, pragmatic randomised controlled study across seven NHS England sites. 222 participants aged 18 to 60 years with FAI syndrome confirmed clinically and radiologically were randomised (1:1) to receive arthroscopic hip surgery (n = 112) or physiotherapy and activity modification (n = 110). We previously reported on the hip outcome score at eight months. The primary outcome measure of this study was minimum Joint Space Width (mJSW) on Anteroposterior Radiograph at 38 months post randomisation. Secondary outcome measures included the Hip Outcome Score and Scoring Hip Osteoarthritis with MRI (SHOMRI) score.

Minimum Joint Space Width data were available for 101 participants (45%) at 38 months post randomisation. Hip outcome score and MRI data were available for 77% and 62% of participants respectively. mJSW was higher in the arthroscopy group (mean (SD) 3.34mm (1.01)) compared to the physiotherapy group (2.99mm (1.33)) at 38 months, p=0.017, however this did not exceed the minimally clinically important difference of 0.48mm. SHOMRI score was significantly lower in the arthroscopy group (mean (SD) 9.22 (11.43)) compared to the physiotherapy group (22.76 (15.26)), p-value <0.001. Hip outcome score was higher in the arthroscopy group (mean (SD) 84.2 (17.4)) compared with the physiotherapy group (74.2 (21.9)), p-value < 0.001).

Patients with FAI syndrome treated surgically may experience slowing of osteoarthritisprogression and superior pain and function compared with patients treated non- operatively.

Introduction: Acquired pes planus is caused by mechanical uncoupling of the bones of the tarsus due to failure of the osseoligamentous complex that maintains the medial longitudinal arch of the foot. The most common cause of acquired flat foot deformity in adults is posterior tibialis tendon dysfunction. A solitary previous case report has documented an alternative aetiology of acquired flat foot in adults due to isolated spring ligament rupture; in that case diagnosis was made intra-operatively.

Materials and Methods: We present 9 cases of acquired flat foot deformity that were caused by isolated spring ligament insufficiency, mainly presenting after an eversion injury of the ankle. We present the clinical sign of ability to single leg tiptoe, but with persistent forefoot abduction and heel valgus, that allows differentiation of this diagnosis from posterior tibialis tendon dysfunction. In addition we illustrate the radiological features of this condition which have not been previously described and allow confirmation of the diagnosis non-operatively.

Results: Six patients have been managed with orthotics and three underwent surgery; one patient who presented early had an isolated repair of the spring ligament complex and has done well. The remaining two patients required a calcaneal osteotomy and Flexor Digitorum Longus transfer as for a PTT reconstruction. In all these three patients the spring ligament was found to be completely ruptured during surgery.

Discussion: This type of injury may not be as rare as previously thought and demonstrates the importance of the spring ligament on its own in maintaining the medial longitudinal arch. Awareness of this condition could lead to earlier diagnosis and better prognosis with earlier treatment.

Conclusion: We propose that early diagnosis (with ultrasound confirmation) and management of this condition would offer a better prognosis and allow less interventional surgery.
